Abstract

Soil Moisture and Vegetation Growth are the most important and direct index in drought monitoring, and the spectral interpretation of vegetation and soil are serious factors in the judgment of drought degree. Based on the spectral character of water, recently, a new model of Surface Water Capacity Index (SWCI) has been put forward, and the index is more sensitive to the surface water content, and suit for regional drought monitoring. The comparative analysis showed: SWCI is more sensitive than NDVI to monitoring surface soil water content; this is available in real-time soil drought monitoring.
